tracing: Fix possible out of bounds memory access when parsing enums The code that replaces the enum names with the enum values in the tracepoints' format files could possible miss the end of string nul character. This was caused by processing things like backslashes, quotes and other tokens. After processing the tokens, a check for the nul character needed to be done before continuing the loop, because the loop incremented the pointer before doing the check, which could bypass the nul character.
